Park Sooyeon, 22 yrs old, wakes up with an aching hangover and a man's jacket in her arms. In a flash, she grabs her phone to find out what happened the night before. Unfortunately none of her friends remembered anything except the fact that they got a little to excited with the alcohol. Just as Sooyeon was about to give up on finding the owner of the jacket on her bed, her phone lit up with a text message from an unknown number.
"Long time no dare, Ms Ponytail."
On the other side of the message, sat an anxious 'Shadow' and a stunned puppy *cough cough* I-I mean his best friend.
Just another romantic "marry-the-king-of-the-underworld" story, I guess.
